BACKGROUND ART

In general, a conventional charge settlement method of a commercialtransaction which is implemented for purchasing or selling a merchandisehas been mostly performed by cash or a credit card possessed by an user.In case of using a credit card, the user presents a credit card afterpurchasing a merchandise or receiving a service, and then a storerequests and receiving an approval to/from a transaction server using aninquiry terminal installed thereof.

However, the credit card which should be possessed for using thistransaction is easy to be frequently lost, the fact of losing is notaware easily because it is used in large amount transaction more thandozens of thousands won rather than small amount transaction the suchthat the frequency of use is low when it was lost, thereby it isfrequent that the lost credit card is used in a malicious transactionsuch as an unlawful transaction in real state during without recognitionof losing.

And, since the credit card accompanies a commercial transactionaccording to information stored by a magnetic strip method, it is weakto forgery and alteration, thereby damages more than dozens of millionwon are occurred by forged and altered credit card.

Even if not the above losing or forgery and alteration, the credit cardnumber and the term of validity is sufficient for transaction forpurchasing a merchandise at present when shopping through Internet is adaily work, and these information is easily exposed from an onlineshopping mall or a store during transaction by the credit card, therebycases of taking unlawful profit in an Internet shopping mall arefrequently occurred by using these information maliciously and damagesare increasing in the real state.

In this reasons, a purchaser possessing a credit card does not trust theInternet shopping mall to dislike providing their credit card. Thusthere is inconvenience that needlessly large amount of money should bepossessed, or large amount of time should be spent for purchasingnecessary merchandise because purchase through communication network isnot considered. It is a real state that these problems are obstacles toprogress toward a credit society.
